The most dangerous components of sunlight entering our eyes are the spectra in the Ultra Violet range. Ultra-Violet light is broken down into four parts, referred to as UV-A, UV-B, UV-C and UV-D. They each represent a range of wavelengths of light within Ultra-Violet light. The ability to block 100% of all four parts of Ultra-Violet light is referred to as UV400.
